By "Evolved" Square Enix means 'de-evolved into a bland action mech shooter'... then you would have to ask yourself, "Do I like bland mech shooters?"
Personally, I've played better and I found the gameplay meh-tastic, the storyline picked from a slew of cliche of stories all done better than this, and the characters about as one-sided as they come. I can only answer for roughly 5 hours of playing the game, so if any of this changes then I couldn't sit through the bad parts long enough to get to the good ones. Even at $12.50 I would hardly say the game is worth getting.
